Tamarack Mill Dumped Pollutants Into the Weiser River for Years and Paid $45,000 to Walk Away
A sawmill in New Meadows, Idaho racked up 13 separate Clean Water Act violations over nearly four years, discharged illegal process wastewater into a river connected to the Snake River, and settled the whole thing without admitting a single fact.
What $45,000 Does Not Cover
There is a river in western Idaho called the Weiser. It runs through canyon country and ranch land and eventually merges with the Snake River, feeding one of the longest river systems in North America. People fish it. Wildlife drink from it. Downstream communities depend on the same water table it feeds. The Weiser is not an abstraction. It is a physical place where the consequences of Tamarack Mill’s conduct arrived without warning and without consent.
From October 2019 until federal inspectors finally showed up in May 2023, the Weiser River received whatever Tamarack Mill sent its way. Process wastewater from industrial operations. Stormwater contaminated with ash residue, visibly discolored as it ran through piles of sawdust. Runoff from a scrap boneyard filled with old equipment and debris. Oil from a containment structure with a leaking release valve, confirmed by stained soil at the scene. The contamination was not hypothetical or incidental. The inspectors saw it. They documented it. It was there.
What the $45,000 settlement does not account for is the three and a half years before the inspection. Nobody from the federal government checked on this mill between whenever Tamarack Mill first obtained its permit and the day inspectors drove out to 3555 Highway 95 South in May 2023. During that entire stretch, the company was supposed to be policing itself. It was required to send quarterly inspection reports to regulators, collect water samples from all four outfall points, document its oil spill response procedures, train its employees, and submit discharge monitoring reports within 30 days of receiving lab results. It did almost none of this. And nobody outside the company knew, because the company was the one responsible for telling the government what it was doing.
The people who live downstream of the Weiser River did not receive a notice in the mail. They did not get a phone call. There was no public sign posted at the facility disclosing that it held an industrial stormwater discharge permit, because Tamarack Mill violated the rule requiring exactly that sign. The public’s legally guaranteed right to know that an industrial facility was discharging into their watershed was erased by the simple act of not putting up a placard. That is not a paperwork error. That is a choice.
Rodney Krogh, president of Tamarack Mill, LLC, signed this settlement. He signed it acknowledging the EPA’s jurisdiction. He signed it agreeing to pay $45,000. He did not sign anything admitting that a single one of the 13 violations the EPA documented actually occurred. That is what the legal phrase “neither admits nor denies” means in practice: the river got what it got, the company paid a number that works out to roughly $35 per day of the violation period, and everyone moves on.
What the Government Actually Found and Put In Writing
The following are verbatim excerpts from the EPA Consent Agreement filed September 24, 2025, Docket No. CWA-10-2025-0159. These are not allegations by a third party. They are the EPA’s own documented findings, signed by both the company’s president and the EPA Region 10 Director of Enforcement.
“The EPA alleges that Respondent violated the CWA by discharging process wastewater from the Facility into the Weiser River without authorization.”
β Consent Agreement, Part III, Violation 1 (Β§ 3.27)
- Process wastewater is industrial discharge, meaning it originated from the mill’s actual manufacturing operations, not just rainwater running off a parking lot. Discharging it without authorization is a direct violation of Clean Water Act Section 301, the core prohibition of the entire law.
- The Weiser River is confirmed in the same document to be a federally protected navigable water, connected to the Snake River at river mile 445.5, bringing it under the full force of federal jurisdiction.
“The EPA alleges that Respondent violated Part 2.1.2.4 of the MSGP by failing to properly respond to oil leaks and spills, as evidenced by stained soil adjacent to the release valve for the secondary containment structure.”
β Consent Agreement, Part III, Violation 4 (Β§ 3.34)
- Stained soil is physical, permanent evidence of a spill that was not cleaned up. The permit required a written spill response plan, equipment for containment, and actual cleanup. The stain confirms that none of those procedures were followed.
- The secondary containment structure is specifically designed to prevent oil spills from reaching the environment. The leak was at its release valve, the one component whose entire purpose is preventing discharge. The failure is not incidental.
“The EPA alleges that Respondent violated Part 8.O.4.11 of the MSGP by failing to properly manage ash at the Facility, as evidenced by discolored water flowing through a sawdust storage pile with ash residue at the time of inspection.”
β Consent Agreement, Part III, Violation 11 (Β§ 3.51)
- The inspector observed this contamination in real time during the May 22, 2023 visit, meaning it was an active discharge event, not a historical one. Ash residue in stormwater flowing toward the Weiser River’s four outfall points carries heavy metals and alkaline compounds that alter water chemistry and harm aquatic life.
- This was not a hidden or hard-to-detect condition. Visibly discolored water flowing through a storage pile is something anyone walking the site would see.
“The EPA alleges that Respondent violated Parts 3.2.1 and 3.2.3 of the MSGP by failing to complete visual assessments for any quarters in 2020, the second quarter in 2021, the third and fourth quarters in 2022, and first and second quarters in 2023.”
β Consent Agreement, Part III, Violation 6 (Β§ 3.40)
- A visual assessment requires collecting a water sample from each of the four outfall points and documenting what it looks like. Tamarack Mill skipped this entirely for all of 2020, parts of 2021, and the better part of 2022 and 2023. That is a combined total of at least nine quarters with zero documented water quality observations from a facility actively discharging into a federal waterway.
- Without these records, there is no independent evidence of what contamination levels looked like during those periods. That absence of data benefits the company and no one else.
“Respondent neither admits nor denies the specific factual allegations contained in this Consent Agreement.”
β Consent Agreement, Terms of Settlement (Β§ 4.2)
- This single clause means that despite the 13 documented violations, the stained soil, the discolored water, and the years of missing reports, Tamarack Mill has no legal obligation to acknowledge any of it happened. The settlement resolves the civil penalty claims and nothing else.
- The company waived its right to appeal or challenge the Final Order (Β§ 4.15), but it also waived any admission of the underlying conduct. It paid to close the case, not to accept responsibility.
Who Pays When Corporations Don’t
Environmental Degradation
Four outfall points. Three and a half years. The Weiser River received whatever Tamarack Mill discharged, including industrial process wastewater that was never authorized under any permit.
- Unauthorized process wastewater discharge went directly into the Weiser River from industrial sawmill operations. Process wastewater from sawmills and cogeneration plants can carry wood-processing chemicals, suspended solids, and biological oxygen demand that depletes dissolved oxygen and kills aquatic organisms.
- Ash residue contamination was visually documented in real time during the inspection, with discolored water running through a sawdust storage pile. Ash from biomass combustion contains heavy metals including arsenic, cadmium, and chromium, which bioaccumulate in fish and invertebrates.
- Oil and petroleum contamination from unaddressed spills at the secondary containment structure reached stormwater pathways. Petroleum compounds in waterways suppress aquatic insect hatches and are acutely toxic to juvenile fish, which are particularly vulnerable in the Weiser River’s riparian zones.
- Scrap yard (boneyard) runoff from relict equipment and debris leached into stormwater flows at the facility. Old machinery in outdoor storage areas contains oils, lubricants, rust, and degraded metals, all of which migrate into drainage channels during rain events.
- The Weiser River connects to the Snake River at river mile 445.5. The Snake River is a critical migratory corridor for Chinook salmon, steelhead, and other species already listed under the Endangered Species Act. Industrial contamination entering the Weiser does not stay in the Weiser.
- Nine quarters of missing visual assessments from all four outfall points mean there is no documented record of what contamination levels looked like for the majority of the violation period. The true environmental impact of this discharge history cannot be reconstructed.
Public Health
The communities downstream of the Weiser River had no access to the monitoring data that should have been generated quarterly, because that data was never created.
- No public notice was posted at the facility disclosing its industrial stormwater permit, a requirement specifically designed to enable public awareness and participation in environmental oversight. Community members downstream had no legal notice that a permitted industrial discharger operated upstream of them.
- Ash residue in waterways poses direct public health risks for downstream communities that use the Weiser River for recreation, livestock watering, or irrigation. Heavy metals from ash bioaccumulate up the food chain, including in fish that local residents consume.
- No employee training documentation was maintained for workers required to conduct spill response and stormwater inspections. Untrained workers responding to industrial spills may worsen contamination events or fail to report them at all.
- Process wastewater discharge can include chemical oxygen demand loads high enough to trigger algal blooms downstream during warm months. Cyanobacterial blooms produce toxins that cause liver damage and neurological effects in humans and animals that contact or consume affected water.
Economic Inequality
The penalty structure of the Clean Water Act’s administrative enforcement process systematically advantages industrial operations over the communities and ecosystems they affect.
- The $45,000 settlement is the cost of eliminating over three years of documented violations. For a facility that produces dried lumber for commercial sale and sells surplus electricity off-site, $45,000 represents an operating cost, not a deterrent.
- The law caps Class II administrative penalties at $342,218 total, regardless of how many days of violations occurred. A company that violates its permit every single day for three and a half years faces the same maximum administrative penalty as one that violated it for a week.
- The “neither admits nor denies” settlement structure protects the violating company from civil liability in follow-on lawsuits by preventing a finding of fact. Communities seeking independent damages through litigation would have to re-prove every violation from scratch, a cost that is prohibitive for most rural Idaho residents.
- The costs of environmental degradation, including reduced fish populations, contaminated recreational water, and potential health effects, are externalized entirely onto downstream communities and taxpayers. These costs do not appear in the $45,000 penalty figure.
- New Meadows, Idaho is a small rural community. The people most directly exposed to Weiser River contamination are the least likely to have the legal resources or political access to demand accountability beyond what a federal administrative consent agreement provides.
The Price of Polluting the Weiser River for 1,278 Days
The total civil penalty assessed for 13 Clean Water Act violations spanning approximately 3 years and 7 months of documented non-compliance at a facility discharging industrial pollutants into the Weiser River watershed.
That works out to approximately $35.21 per day of the violation period. The law authorized up to $27,378 per day.
By comparison: the EPA’s own statutory maximum for this class of violation was $342,218. Tamarack Mill paid 13.2 cents per dollar of what the law allowed the agency to demand.
The gap between assessed and maximum penalty: $297,218 that could have gone toward watershed restoration, aquatic habitat monitoring, or downstream community water quality programs. It did not.
Who to Hold Accountable and How to Push Back
The people directly responsible for Tamarack Mill’s operations have names. The government agencies empowered to pursue stronger action have addresses and public comment processes. The settlement may be signed, but the compliance obligations are ongoing.
The Named Decision-Maker
- Rodney Krogh, President, Tamarack Mill, LLC signed the consent agreement. As the authorized representative of the company, he certified that Tamarack Mill is “addressing the violations alleged” per a companion compliance order, Docket No. CWA-10-2025-0158. That order can be requested through EPA Region 10 via public records requests to confirm what corrective actions were actually required and whether they have been completed.
Regulatory Watchlist
- EPA Region 10, Enforcement and Compliance Assurance Division: The division that brought this case, led at signing by Director Edward J. Kowalski. Region 10 covers Idaho, Oregon, Washington, and Alaska. Their public records can be requested to track ongoing compliance at Tamarack Mill, including whether inspections are now occurring. Contact: 1200 Sixth Avenue, Suite 155, Seattle, WA 98101.
- Idaho Department of Environmental Quality (IDEQ): Idaho runs its own NPDES permitting program (Idaho Pollutant Discharge Elimination System), approved by the EPA in 2018. IDEQ has independent authority to monitor Tamarack Mill’s stormwater permit compliance and can be contacted to request copies of any state-level inspection records or permit renewal documents.
- EPA ECHO Database (Enforcement and Compliance History Online): The public-facing federal database where discharge monitoring reports, inspection records, and enforcement actions for facilities like Tamarack Mill are supposed to be posted. Search for NPDES permit number IDR053165 to track future compliance reporting. If monitoring reports go missing again, ECHO is where you would first see it.
- U.S. Army Corps of Engineers, Walla Walla District: The agency responsible for oversight of the Snake River downstream, including the reach at river mile 445.5 where the Weiser connects. Documented upstream contamination can be reported to their regulatory office for independent assessment of downstream impacts.
Grassroots and Mutual Aid Action
- Request the companion compliance order. Docket No. CWA-10-2025-0158 is a separate Administrative Compliance Order on Consent that specifies what Tamarack Mill must actually do to fix the violations. It is a public record. File a Freedom of Information Act request with EPA Region 10 at R10_FOIA@epa.gov to obtain a copy and verify that required corrective actions are being implemented and on schedule.
- Connect with the Idaho Conservation League, the state’s most established watershed advocacy organization, which has a track record of monitoring industrial stormwater permits and has litigated violations on Idaho rivers including the Snake River system. Share this case documentation with them directly.
- Attend Adams County (Idaho) local government meetings and ask your county commissioners to formally request an IDEQ briefing on current Tamarack Mill compliance status. New Meadows sits in Adams County. Local government pressure creates public record and forces agency staff to document their responses.
- Monitor Tamarack Mill’s NPDES permit renewal. Industrial stormwater permits under the MSGP have defined coverage periods. When Tamarack Mill’s permit comes up for renewal or re-authorization, the public has the right to submit formal comments requesting stronger monitoring requirements or additional discharge limits. Subscribe to EPA Region 10 public notices to catch the renewal window.
- Document your own observations. If you live, work, or recreate near the Weiser River downstream of the Highway 95 area in New Meadows, photograph any visible discoloration, foam, or unusual conditions and report them to both the EPA Region 10 Tip Line (1-800-424-4372) and IDEQ (208-373-0502). Citizen documentation has triggered federal enforcement actions before and can do it again.

However the reason why I specified the 2025 link was above is because 10 years ago, this exact same evil corporation in New Meadows, Idaho named Tamarack Mill had another consent agreement with the EPA for completely different pollutions: https://yosemite.epa.gov/OA/RHC/EPAAdmin.nsf/Filings/75B56FA2A6C7945085257F1C0021479F/$File/CWA-10-2016-0031%20CAFO_OCR.pdf
